Iodine Half-Life Experiment. Iodine is element number 53. That is, Iodine has 53 protrons and 53 electrons. That is what determines that it is Iodine. We could also say that for Iodine, Z = 53. How many neutrons does Iodine have? Most naturally-occuring Iodine is Iodine-127. We could say A = 127. Remember, A is the atomic mass number of an isotope -- the total number of nucleons inside the nucleus. A is the total number of the protons and neutrons inside the nucleus, A = Z + N. N = A - Z. N = 127 - 53. N = 74. Most naturally-occuring Iodine has 74 neutrons. We can write this as. 127 I 53. What happens if this naturally-occuring Iodine-127 absorbs a neutron?
Best Answer: Iodine is one of those few elements that has only one stable isotope. There are over 40 isotopes of I, but only one stable isotope, and it has a mass number of 127. The remaining isotopes of iodine can have a wide range of mass numbers. http://www.dayah.com/periodic/ indicates that there are mass numbers for iodine from 108 to 144.
